MACHINE FOR SHAPING UPPERS OVER LASTS Filed May 25, 1942 5 Sheets-Sheet5 Patented Aug. 24, 1943 MACHINE FOR SHAPHNG UPPERS OVER LASTS Corwin W.Baker, Stoneharn, Mass assignor to United Shoe Machinery Corporation,Flemington, N. 3., a corporation of New Jersey Application May 25, 1942,Serial No. Mans 19 Glaims.

This invention relates to machines for shaping shoe uppers over lastsand is herein illustrated as embodied in a lasting machine in the use ofwhich successive portions of an upper are progressively tensioned andworked into lasted position on the insole of a shoe.

The object of the invention is to provide an improved machine, simple inconstruction and operation, for lasting in a quick and effective mannershoes in Which cement is used to secure the overlasted margin of theupper to the insole.

With this object in view, a feature of the invention resides in thecombination with means operating intermittently to grip and pullsuccessive portions of an upper over a last, of means actingsubstantially continuously on the previously cemented margin of theupper, adjacent to the pulling means, to wipe the margin inward over aninsole on the last while imparting to it a plurality of pressureimpulses, heightwise of the last. In the illustrated machine, the marginlaying means consists of a continuously driven rotary wiper having uponits periphery spaced projections so that it not only wipes the margin ofthe upper overthe insole but continuously pounds or subjects said marginto a rapid series of pressure impulses. This wiper mechanism, as shown,is similar to that disclosed in my prior application for Letters Patentof the United States, Serial No. 403,737, filed July 23, 1941.

According to the present invention, however, the upper gripping andtensioning means consists of a pincer which operates intermittently togrip and pull the upper, in contrast to the gripper rolls in the machinedisclosed in my said prior application, which rolls operatecontinuously.

Invention is also to be recognized in a mounting for such a pincerconstructed and arranged to permit the pincer jaws to oscillate about anaxis parallel to the bottom face of the insole of a shoe being operatedupon and transverse to the shoe, to cause the upper to be simultaneouslytensioned heightwise of the last and the shoe to be fed progressivelythrough the machine.

A further feature of the invention resides in such an oscillatablepincer constructed and arranged also to permit movement of its jawsradially of their normal arcuate path of movement as may be needed toincrease the tensioning effect upon the shoe upper. In the machine shownin the accompanying drawings, manual means is provided for varying theextent of the radial movement of the jaws so that the tensioning efiectof the pincer upon the shoe upper may be varied at will by the operator,even while the machine is in operation.

In another aspect, the invention also provides, in combination with thelasting instrumentalities of a lasting machine, a tack pulling tool andmeans for operating the lasting instrumentalities and the tack pullingtool simultaneously. As disclosed herein, the machine is provided withan oscillatory table upon which both the lasting pincer and the, tackpulling tool are carried and with which they oscillate in differentarcuate paths, the tack puller normally moving in a path remote from theshoe and being ineffective but being arranged to be projected at thewill of the operator into operative relation to the shoe.

According to another feature of the invention, a shoe bottom rest,movable between effective and ineffective positions, is provided,together with means for moving it to effective shoe gaging positionduring each pause in the intermittent feeding movement of the shoe andretracting it to ineffective position during each increment of saidmovement.

A still further feature of the invention resides in the provision ofmeans for pressing the mar ginal portion of an insole against the bottomof the last and wiping it out smoothly toward the edge of the last. Thiswiping means preferably operates in advance of the rotary Wiper whichlays the margin of the upper inward over the insole and greatlyfacilitates the production of a smooth shoe bottom when thin or softinsoles are used, they frequently having a tendency to become bunched upat spots, preventing the accomplishment of a perfect lasting operation.

The above and other features of the invention and benefits to be derivedfrom its use will appear more clearly in the following detaileddescription of one embodiment thereof when read in connection with theaccompanying drawings, in which Fig. 1 is a view of the machine in frontelevation;

Figs. 9, 10, 11 and 12 show views of details of the mechanism shown inFig. '1.

Referring now to the drawings, I indicates a supporting column uponwhich is mounted a frame or casing I2 containing the operating mechanismof the machine. Power is supplied to the machine by a driving belt I4which engages a pulley I6 upon a main shaft I8 running in bearings 20formed in the stationary frame I2.

A gear 22 (Fig. 1) afflxed to the shaft I8 meshes with, and drives, asimilar gear 24 secured to a countershaft 26 upon which is an eccentric20 (Figs. 3 and 4). The eccentric 28 is connected by an eccentric rod 30through a ball and socket joint 32 to the outer end of a swinging arm 34having a split hub 36 which is secured by a clamping bolt 38 upon thelower end of an upright sleeve 40.

Mounted upon the upper end of the sleeve 40 is a table 42 which supportsand imparts swinging movement to a pincer 44 and a tack pulling tool 46when the sleeve 40 is oscillated about its vertical axis. The pincercomprises a stationary upper Jaw 48 and a movable lower jaw 50'. Thelower Jaw 60 is mounted for pivotal movement about a horizontal stud 52(Fig. and the rear end of the jaw member carries a, laterally projectingpin 54 to which is pivotally connected a vertical rod 56 passingdownward through the sleeve 40. The lower end of the rod 56 rests in asocket member 58 (Figs. 1, 3 and 6) adjustably threaded through an ear60 which is a part of an arm 62. The arm 62 is bifurcated and mounted toswing vertically about a horizontal pivot pin 64 mounted in a stationarybracket 66 which is bolted down to the machine frame.

A stiff compression spring 68 surrounds the rod 56 and bears upon awasher I0 supported by a nut I2 threaded upon the lower end of the rod.By adjustment of this nut the tension of the spring can be varied. Thespring 68 tends to close the pincer 44 and to hold the lower end of therod 56 down in engagement with the socket member 58.

In order to provide for opening the pincer when it is desired to inserttherein the margin of a shoe upper, as the shoe is presented in theposition shown in Figs. 2 and 3 with the bottom face of the insoleparallel to the axis of the sleeve 40 and the shoe disposed transverselyto said axis, there is provided a rod 74 the, lower end of which passesloosely through a hole in an ear it formed on the arm 62 and has a nuti8 screwed upon its lower end. The upper end of the rod I4 is pivoted at80 to a rocker arm 82 mounted upon a rockshaft 84 to which is secured alever 86 having its outer end connected by a treadle rod 08 to a treadle(not shown). When the treadle rod 88 is lowered by depressing thetreadle the rod I4 will be raised and the arm 62 will be lifted, therebylifting the pincer rod 06 and opening the pincer against the tension ofthe spring 68.

In order to open and close the pincer intermittently during theoperation ofthe machine, the front end of a lever 00, pivoted upon thepin 64 between the arms of the bifurcated portion of the arm 62, isarranged to engage the under side of the said arm and the rear end ofthe lever carries a cam roll 02 (Figs. 3 and 6) which engages a cam 94upon the shaft 26, the roll being held against the cam by a springpressed plunger 96 housed in the lever 90 and bearing upon the base ofthe bracket 86. The cam 0415 so timed relatively to the eccentric 28that it will cause the pincer to be opened at the end of its horizontalswinging movement in one direction and held open while it is returned toits starting position, whereupon it will be closed to secure a new gripon the margin of the shoe upper, it being understood that the horizontaloscillatory movement of the pincer in an arcuate path is for the purposeof feeding the shoe progressively past the tools which operate upon itas well as to tension the upper.

For the purpose of further tensioning the shoe upper about the last thepincer is carried by a reciprocatory slide 98 connected by a link I00 toa pivot IOI on a block I02 which is slidable in an arcuate guideway I04in a rocker member I06 aflixed to the upper end of an upright rockshaftI08. Secured to the shaft I08 by a clamping bolt IIO passing through asplit hub II2 (Fig. 4) is a swinging arm II4 which is connected by alink II6 to an arm II8 integral with the swinging arm 34 but extendingin the opposite direcgim therefrom relative to the axis of the sleeveThe reason for the slidable block I02 is to provide for adjustment ofthe eccentricity of the pivot IOI relative to the axis of the shaft I08and to this end the block is connected by a link I20 to a lever I22movable about a stationary pivot I24 and connected, in turn, by a linkI26 to an upright arm I20 of a bell crank lever movable about astationary horizontal pivot pin I80. The second arm I32 of the bellcrank lever is connected by a treadle rod I34 to a treadle (not shown)by the actuation of which the block I02 may be 50 adjusted lengthwise inthe guide I04 that the pivot IOI is either concentric with the axis ofthe shaft or eccentric thereto by any desired amount. The shifting ofthe pivot IOI may be effected at any time and to any desired extent,regardless of whether the machine is running or not, and when the pivotis offset from the axis of the shaft I08 the rocking movement of thesaid shaft, derived from the arm H8 and transmitted by the link II6,will cause the slide 98 and the pincer carried thereby to bereciprocated in proper time relation to the movement of the otherelements of the mechanism, to exert additional pull or tension upon theshoe upper in the grip of the pincer during each increment of the workfeeding movement, the length of the pincer stroke being determined bythe distance iaaggween the pivot WI and the axis of the shaft Inaddition to the slide 98 there is mounted upon the table 42 a box-likguide member I38 in which is a longitudinally movable slide bar H8. Thetack pulling tool 46 is secured to the front end portion of the bar I38by a screw I40 and a compression spring I42 housed in a bore in the bartends at all times to move the bar rearward to the retracted positionshown in Figs. 2 and 4 in which position the tack puller is ineffective.A roll I43 upon the rear end portion of the bar is arranged to beengaged by a cam face I44 formed upon an arm I46, one end of which ismovable about a stationary pivot I48 and the other end of which isconnected by a link I60 to an arm I52 of a bell crank lever movableabout a stationary pivot I54 and having its other arm I56 connected by alink I58to an arm N0 of another bell crank lever pivotally mounted uponthe pin I30. The second arm I62 of the last-named bell crank lever isconnected by a,

treadle rod i to a third treadle (not shown) by actuation of which,through the connections just described, the arm M6 may be swung forwardabout the pivot lit to cause the cam face Mi t to enga e the roll litand project the bar tilt and the tack pulling tool tit forward tooperative position where it can operate to pull out any pulling overtacks that may project from the bottom oi the shoe.

it bottom rest Iii-lb by which the position oi shoe relatively to thepincer it is gaged is mounted upon the front end of a slide Elba, guidedtor rectilinear movement fore and aft of the machine in a stationarybox-like guide ilii (Figs. 1 and 8) bolted down upon the machine frameby bolts ilft. ihe rearend of the glide tilt is connected by a link lidto the upright arm ilii of a bell crank lever which. is movable abouthorizontal pivot il't carried by a stationary bracket itilll which isalso bolted to the machine frame. At the rear end or the second arm i832oi the bell crank lever is a cam roll id l which is held in engagementwith the cam so by a spring iliii (Fig. 3) enclosed in a stationaryhousing its and bearing upon a boss tilt formed upon the arm Hill.

The stroke of the bottom rest ltd is short and the purpose in keeping itcontinually recip rocating is to facilitate the movement of the shoe asit progresses during the lasting operation. The timing is such that thebottom rest will be projected forward to effective position in contactwith the shoe bottom in the period when the pincer jaws are open,between successive movements of the shoe, and will be retracted a shortdistance to ineilective position while the jaws are closed and the shoeis being fed along.

When thin and soft insoles are used they freauently have a tendency tobecome bunched up at spots, preventing the accomplishment of a perfectlasting operation, and for the purpose of overcoming this trouble I haveprovided a wiper finger use (Figs. 1 and 7) designed to engage and wipethe marginal portion of the in" sole, pressing it against the bottom ofthe last and smoothing it out toward the edge thereof. This wiper fingeris mounted in a rocker member II 92 which is journaled upon a pivotshaft i it secured in a cradle Idi'i.

The cradle tilt is journaled on the forward portion of a hollow sleeveits so as to be capable of oscillatory movement relatively to thesleeve, about the axis of the sleeve. An arm 2% extending rearward fromthe rocker member W2, and integral therewith, contains a compressionspring 282 the lower end of which bears upon the cradle I96 and tends atall times to swing the rocker member relatively to the cradle in acounterclockwise direction, as viewed from the right hand side in Figs.1 and '7. The sleeve I98 is journaled for oscillatory movement in abearing in the frame i2 and has amxed to its rear end portion a rockerarm 204 which is pivotally connected by a ball and socket Joint 2% I a.crank member 2 from the rear face 01' which projects 9. lug 2IB. Figs. 9and 11. This lug is disposed in a radial slot 2m formed in the cred dieiiit, the slot being substantially wider than the lug and the lug beingnormally held against one side oi the slot by a compression spring arecontained in a housing ltd forming part oi the cradle. Thus when thesleeve lid is oscillated it will, through the crank member tit and thelug dill, cause the cradle let to oscillate with the sleeve, about theaxis of the latter. By reason of the yielding connection between thecrank member 2% and the crank its, afforded by the lug tit and thespring 2%. the oscillation of the cradle may be stopped at any time byswinging it a short distance in a clockwise direction as seen from thefront of the machine. For this purpose the cradle is provided with adownwardly ex= tending abutment 22d arranged to be engaged by a bar 226which is pivotally connected at to an arm 2% extending downward from thel ver Elli. When the treadle rod 88 is depressed; therefore, not onlywill the pincer it be opened but oscillation of the cradle tilt and thwiper finger ltd will also be stopped. I

Extending through the bore of the sleeve 095i is a connecting rod 232the front end of which has a socket surrounding the ball end 236 of apin 2% which passes through a supporting. arm

35? journaled upon the pivot shaft ld l. A sleeve 2% surrounding the pinis forced against the ide of the arm 238 by a nut till threaded upon theend of the pin. The sleeve t lt is arranged to be engaged by the hookedend'Z l i of an arm 2%, which is integral with the rocker member tar, asbest shown in Figs. 1, 7 and 12.

The structure just described permits the rocker member W2 and the fingertilt to be oscillated about the axis of the shaft i941 by reciprocationof the connecting rod 232, provision for yielding when the finger Hidencounters resistance being made by the ability of the pin 236 and thesleeve Zliii to leave the hook wi l, these parts being normally held incontact by the spring 202,

The rear end of the connecting rod 232 is pivotally connected by a balland socket joint to an upright arm 2% (Fig. 7) pivoted on a pin 2513supported in a stationary bracket 2E2 bolted to the machine frame.Integral with the arm 2 th is a horizontal arm 2% carrying a cam roll 2%which engages a cam 253 afilxecl to the left hand end portion of thecountershaft 26 (see Figs. 1, 2 and 7). A compression spring 260, Fig.3, contained in a stationary housing 262 bears on the enlarged rear endportion 264 of the cam roll arm 25%, holding the cam roll in engagementwith the cam.

The cam 258 is so timed relatively to the eccentric 28 that the wiperfinger I90 will be simultaneously rocked, about the pivot shaft I94,into engagement with the insole of the shoe and, about the axis of thesleevel98, toward the edge of the last, while the pincer M is movingtoward the left, as viewed in Fig. 1, during which time the pincer ispulling the upper over the last and feeding the shoe leftward. Thefinger I90 thus wipes out the marginal portion of the insole smoothlyagainst the bottom of the last in ad- Vance of the engagement of themargin of the shoe upper by the upper margin laying means 214 presentlyto be described.

An edge gage roll 266 for determining the position of the shoevertically in relation to the pincer 44 is carried by a rod 268supported by a bar 210 mounted in a bracket 212 bolted to the machineframe.

A rotary wiper 214, similar in structure and operation to that disclosedin my aforesaid prior application for Letters Patent of the UnitedStates Serial No. 403,737, filed July 23, 1941, is rotatively mountedupon a stud 216 secured in an angle plate 218 adjustable along anarcuate slot 280111 a stationary upright bracket 282. A pulley 284 fastto the rotary wiper 214 receives power from a belt 286 driven by apulley 288 affixed to a countershaft 280 which is continuously drivenfrom the shaft I8 through a belt 282. By adjustment of the angle plate218 along the arcuate slot 280 the plane of the wiper can be adjusted toany desired inclination to the vertical and slots 284 in the base of thebracket 282, through which pass the bolts which secure the bracket tothe machine frame, permit adjustment of the entire wiper supportingstructure horizontally, to vary the distance between the wiper and thepincer 44.

In the normal operation of the machine the shaft I8 is drivencontinuously. The treadle rod 88 is depressed to open the pincer jawsand stop the wiping action of the insole wiper finger I80, permittingthe marginal portion of the shoe upper to be inserted between the pincerjaws with the shoe positioned against the edge gage 268 and in the rangeof operation of the bottom rest finger I66. The treadle to which the rod88 is connected is then released, whereupon the pincer jaws 48, 50 seizethe margin of the shoe upper and simultaneously feed the shoe in thedirection indicated by the arrow upon the shoe in Fig. 2 and tension theupper over the last with more or less force depending upon the positionof the slidable block I02, which may be shifted at will during theoperation of the machine bygreater or less depression of the treadleconnected to the rod I34.-

If there are any projecting pulling over tacks which need to be pulled,the operator depresses the treadle connected to the rod I84 at theappropriate time, thus projecting the tack pulling tool I40 intooperative position where it will engage and pull the tacks.

At the end of the feeding stroke of the pincer 44, toward the left handside of the machine, the pincer jaws open, release the shoe upper, movetoward the right and again close upon the margin of the upper, seizingthe latter at a new place thereon, ready to begin another leftwardfeeding stroke. The action of the pincer upon the work is thuintermittently progressive and as the margin of the upper leaves thepincer it comes into the path of the rapidly rotating wiper 214 whichlays the margin down upon the insole and, by a combined wiping actionand a rapid series of pressure impulses, forces the upper into permanentadherence to the insole, it being assumed that both the upper and theinsole have been previously coated with cement.

During each step of the feeding operation, that is during each leftwardstroke of the pincer, the insole wiper finger I80 swings forward intoengagement with the insole, pressing the latter against the last, andthen, while the pincer is swinging toward the left, the finger alsoswings toward the left and in addition moves upward toward the edge ofthe last, this composite movement being in an arc of a circle about thefixed axis of the sleeve I88 as a center. At about the time when thepincer jaws open, the cam 288 causes the finger I80 to move rearward outof engagement with the insole and holds it thus retracted while theconnecting rod 208 swings it back to its right hand position,simultaneously with the movement of the open pincer jaws toward theirright hand position preparatory to taking a fresh grip on the upper. Byreason of the spring 202 the finger I80 can yield rearward at any timeand will never bear against the work with any more force than thatprovided by said spring.

As the operation proceeds to a portion of the shoe where a stronger pullupon the upper is needed to tension it properly over the last thetreadle rod I34 may be depressed causing the pivot IOI to be displacedfurther from the axis of the shaft I08, with the result that a longertensioning stroke is imparted to the pincer. The tensioning effect isthus increased to the desired extent until a portion of the shoe isreached where less tension is required, whereupon the treadle .48 isreleased. The lasting operation proceeds continuously regardless ofthese changes in the tensioning force applied to the shoe upper.

As is apparent from Figs. 1, 2 and 3, the plane of rotation of the wiper214 is so inclined with respect to the edge of the last that the marginof the upper is wiped both inward and longitudinally of the last, awayfrom the pincer in the direction in which the shoe is moving. The largenumber of pressure and wiping impulses imparted by the projections uponthe wiper cause the upper material to be distributed evenlysubstantially continuously and laid smoothly on the bottom face of theinsole especially when working around curves, as at the toe of a shoe,where the tendency is to produce a large number of narrow pleats orfolds evenly distributed along the curve.
